Xnäyttöpalvelimen

Xnäyttöpalvelimen, often referred to as the X server, is a fundamental component of the X Window System. The X Window System is a network-transparent windowing system used for creating graphical user interfaces (GUIs) on Unix-like operating systems. The X server is responsible for managing the display, keyboard, and mouse, and for drawing windows and other graphical elements on the screen. It acts as an intermediary between client applications and the hardware. Client applications, such as web browsers or text editors, send requests to the X server to draw specific elements or to receive input events. The X server then translates these requests into commands for the graphics hardware and sends input events back to the appropriate client. This client-server architecture allows for network transparency, meaning that an X client application can run on one machine and display its graphical output on another machine connected over a network. Different implementations of the X server exist, catering to various operating systems and hardware configurations. Common examples include Xorg, which is widely used, and older implementations like XFree86. The X server is a crucial piece of software that enables graphical interaction for many users of Linux, macOS, and other Unix-like systems. Its role is essential for the functioning of desktop environments and graphical applications.
